Players often require specific amounts of resources for a multitude of reasons. Whilst other players have such large stacks in storage that they have difficulty moving due to HoFs and ATHs. Placing multiple stacks in the Auction or in Shops fills their limited allotted selling space. I'd like to propose that Shopkeeper / Vending machine type mechanism be instituted where sellers can pre-load stacks and specify a MU, and players could then buy the specific amounts that they require. For example the AUD NPC that used to stand around, vending deeds. There is also the scope that a seller instead of specifying a MU could "tick box" that he / she would like the MU to be the same as the Monthly or Weekly Auction MU, this would prohibit undercutting and limit owner price maintenance.
